Abstract
PURPOSE: To permit the air speed to be accurately measured even if the air flow deflects within certain limits by providing hoods covering the hot and cold junctions of a thermocouple and a heating wire in order to form an air-flow passage crossing the heating wire.
CONSTITUTION: Between the top ends of supports 5 and 6, a heating wire 7 of nichrome is connected. A junction 13 of the first and second thermocouple-wires 10 and 12 which has the same temperature as the center of the heating wire 7 cooled according to the speed of an air flow F is the hot junction of a thermocouple 10, 8, 9 and 12 for measuring the air speed, and a junction 14 of the second thermocouple- wire 12 and the second support 9 which has the same temperature as the air flow F if the cold junction of the thermocouple 10, 8, 9 and 12 for correcting the air temperature. To use this detecting body, a power source 21 is connected to measure 22 the thermoelectromotive force of the thermocouple 10, 8, 9 and 12. The apparatus is covered with hoods 15 and 16 to form an air-flow passage 18, so that an accurate measurement can be performed even if the direction of the air flow F deflects within certain limits.
